The archives received a copy of the September 2011 issue of Mathematics Teacher, a journal of the National Council of Teachers of Mathematics (NCTM).  Fr. Arnold Perham, CSV, and his sister, Faustine Perham, professor emerita at the University of Wisconsin-Whitewater, co-authored the article “Voronoi Diagrams and Spring Rain” on pages 126-132.  A class geometry project used “Voronoi diagrams, a powerful modeling tool across disciplines, and the integration of technology to analyze spring rainfall from rain gauge data over a region.”

Congratulations Fr. Arnie and Faustine!
